A guide to help importers and exporters navigate the supply chain

Navigating the logistics maze can be overwhelming and confusing for first-time shippers. We’re here to help.

In this guide, you’ll find the basics of importing and exporting through The Northwest Seaport Alliance and links to resources that can help you move your cargo.

Importing to the U.S.

All goods that enter the United States must clear U.S. Customs and Border Protection. Import cargo is subject to Customs duty, taxes and fees.

The clearance process involves: entry, inspection, appraisement, classification and liquidation. You will need to declare a value for the merchandise and determine the merchandise classification number.

U.S. Customs and Border Protection recommends using a Customs House Broker. Licensed by Customs, Customs House Brokers are hired by the client to transact Customs business on their behalf in the import or export of merchandise.

A Customs House Broker will:

Help you determine the correct way to classify your shipment

Calculate estimated Customs duties and taxes

Complete/submit Customs paperwork

Act as your agent with transportation providers and Customs

Require a Power of Attorney to transact Customs business on your behalf

Ocean Carriers

A freight forwarder can help book your space with the ocean carrier, or you book space directly with the shipping line. Find the list of Ocean Carriers calling The Northwest Seaport Alliance terminals.
